One of the recycling of power lithium battery: pollution and recycling

　　Author ：Iflowpower – Portable Power Station Supplier

Amounted to a car show in Beijing Mobile, in April 2015, had a listener questioning whether the new energy car really environmentally friendly: "So how many new energy cars, how many crops are contaminated?" With the development of electric vehicles, Future power lithium-ion battery will usher in a huge market, and there will be a large number of recycling problems with a large amount of powerful lithium-ion battery retirement. Although there is an unprecedented opportunity, it also has a new problem that cannot be avoided. This article uses eight keywords recovered by power lithium-ion batteries to systematically explain the opportunities, hidden and response strategies of dynamic lithium-ion batteries.

The article is longer, this article is divided into three articles. This is the first one. Key words: Pollution At present, although the type of battery is wide, it is certain that almost every battery contains one or more harmful substances, these harmful substances, more heavy metals and some kinds of electrolytes.

We have traditional batteries, such as dry batteries, mobile phone batteries, etc. As everyone knows, the way of treatment of domestic garbage is important to landfill, incinerate or compost, etc. Using these ways to process the battery, the harm caused by the natural environment and human health is self-evident.

"A small button battery can pollute the water of 600 cubic meters, which is equivalent to a person's drinking water; one battery is rotated in the ground, can make the 1 square meter land lost value ." It is a parameter in public service advertisements. The number is shocking, but it is not a dramatic.

For example, some used battery electrolytes may alter the soil and water source local acid-alkali, more terrible, is the heavy metal element in the old battery, may be brought into the soil from the surface, and then brought into groundwater from the soil . these Hazardous substances will not only pass the biological chain, may eventually form an enriched in the human body, threatening human health. If the incineration is used, in addition to the above contamination, there may also occur harmful gases such as HF, CL2.

Some people may say that the battery's electrolyte is a little bit of a point, can there be much effect on the acid and alkalinity of the water and soil? Now the total battery is large, never before. For example, mobile phones, tablets, cameras, charging treasures, etc., have high penetration rates.

In terms of smartphone, according to the latest report released by Fortresterresearch, my country's 2015 smartphone will reach 44%, if the average battery capacity of a smartphone is 2000mAh, Replace a mobile phone every two years, only a smartphone, the total amount of waste batteries in my country will exceed 2.2GWH. At this time, the new energy car came again.

In 2014, the sales volume of new energy vehicles exceeded 70,000. If a car is equipped with a 20KWH power lithium-ion battery, then the total amount of power lithium-ion battery equipped with these new energy vehicles has exceeded 1.4GWH, which is with my country.

The Secretary-General of the Chemistry and Physical Power Industry Association, Mr. Liu Yanlong, predicted, roughly the same. More important, in 2014, it is just the first year of new energy cars, everything just started.

At present, the power lithium-ion battery is mainly based on lithium ion batteries and nickel-hydrogen batteries. Someone calls the battery of the ion, called "green battery". The reason is that lithium-ion batteries are not mixed with mercury, cadmium, lead, etc.

, but this does not represent lithium-ion batteries are absolutely non-polluting products, and waste lithium ion batteries can cause extremely to the environment. Big pollution. For example, the positive material of the power lithium-ion battery is still possible to cause heavy metals, and the electrolyte is also very corrosive and toxic, which is easy to have toxic chemical gas.

Keywords: Recycling above, currently the total amount of domestic battery is quite large, but the number of recycled scraps is very small, most of which come from the use of waste or inventory of the production company, directly from the people Less battery. There may be three reasons for this situation: first, waste batteries are too dispersed. Although the total amount of battery in the domestic people has a large amount, each person's waste battery is small, most of the general domestic garbage treatment.

Second, lack of channels. At present, there is no comprehensive battery recycling channel in China. Especially from the eliminated lithium-ion battery of electronics, the value is low, very few special companies go to the recycling process, the people generally will not accumulate unified processing, and finally don't have the same hand to the domestic garbage.

Third, the recycling manufacturers are not good. Domestic regulations have strict regulations on battery recycling companies. The company should apply for the "Hazardous Waste Business License" to engage in waste battery recycling and processing work.

However, due to the problems of technology and funds, there are not many companies with qualified recycling qualifications. Conversely, many individuals and unsupported companies, not only low technology, but also destructive environmental pollution to rescue recycling batteries. They recycle old batteries at a higher price, not only disrupted, but also have a large environment and safety hazard.

In the next few years, this situation may change. There is currently no large quantity of powerful dynamic lithium-ion batteries from new energy vehicles, as new energy owners, individuals may have hundreds of kilograms of used batteries to be dealt, these used batteries are also difficult to dispose. At that time, the good work of the dynamic lithium-ion battery in the life of life may become another important factor affecting the development of new energy vehicles.
